Tim Moorey has most unusually got me stumped - 11 across (4,8) Due to being ruined as before Essex Town engages names in Friends of the Earth ?RO? F?R??NNE; 12 across (4) Old opponents mobile so to speak ?ON? and 15 across (5) German green campaigner on a great deal that's cut ??ALO - can anyone throw any light on these - Have been racking my brain for hours (had the rest of it done quite quickly)
